Rotor has relaunched the Uno groupset platform today, only this time it has embraced electronic technology and ditched the previous 13-speed hydraulic system.
Rotor first launched the hydraulic Uno groupset back in 2015; for the most part, it seems to have remained an interesting, alternate option rather than properly challenging offerings from the likes of Shimano, SRAM or Campagnolo, but never really took off.

Both groupsets focus on 1X, single-ring offerings currently. There is already a range of rotor crankset options to pair the systems with, such as the Rotor Aldhu carbon fibre cranks, but other cranksets could be used.

The brake levers, which look similar to SRAM units, feature carbon fibre…
